two forces 5n and 4n are inclined to each other at 30 degree find the resultant force and its direction to the horizontal force of 5n.

Answer 1

horizontal component = 5 + 4 cos 30 = 8.46
vertical component = 4 sin 30 = 2
magnitude = sqrt (4 + 8.46^2)
angle above horizontal = tan^-1 ( 2/8.46)

Answer 2

8.697
